Appneati'uii'ea December 5, 1917. seril 110.205,636;

To all whom it may concern.'

Be it known that I, JOI-'IN VIDAL, a citizenJ of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements 1n Embroidery-Frames, of

Which the following is a specification.

This invention relates to embroidery frames or the like and has 'for its principal object the provision of means for securing the cloth in position upon the frame so as to prevent marring of the edges thereof'and at the same time furnishing means; Whichcan be expeditiously adjusted topermit of' the application of the cloth to or removal of the same from the frame.

Another object of the invention're'sides -m' the provision of a device of this character an applied position, supplementingV said' means With a tensioning device' wherebythe means may be brought under the requisite tension to positively assure retention of the cloth in the groove. i

With the above and otherobjects in view Which Will appear as the natureI of the kin-y vention is better understood, the same consists in the improved construction'and'novel' arrangements' of parts which Will hereinafter be fully described and particularly pointed out in the claims.

In the accompanying drawings-hasbeen illustrated,-a single and preferred form of the invention, it being, however, understood that no limitations are necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications Within the scope of the claims" may be resorted to when desired.

Figure 1 is a plan view of the frame.

Fig. 2 is a side view thereof.

Fig. 3 is an end vievv thereof.

Fig. 4 is a sectional perspective view of a portion of the frame.

Fig. 5 is a transverse section through one of the bars of the ,frame Fig. 6 is a horizontal section through one V of the'bars of the frame showing the ten-l sioning mechanism and flexible retainer.

F ig'. Tis a similar View Showing a slightly modified form of the invention.

The invention, While being; particularly applicable for use in connection With embroidery frames, is nevertheless most effective for the'purpose generally of clamping cloths, hides, and the like in usual stretching frames and the like.

broidery frames'.

Structurally, the frame shown herein consists of side bars 8 8, and end bars 9 9,

each having a continuous slot 10, therein. The end bars are adjustable angularly with relation tothe side bars through the slotted formation described, the. said slots receiving clamping bolts 11, of any suitable Well known design which can be actuated to permitk various adjustments ofthe frame to be made and Which will also `operate to hold the mating. bars of the frame in relatively fixed positions after a desired adjustment has been obtained.

The essential feature of the present, invention resides 1n mechanism for clamping thev cloth in the frame. In order1 that this can be accomplished Without marring the edges ofthe cloth, and the marginal edges of the latterv uniformly held in a firmly clamped position upon the frame, I provide each of the mentioned bars 8 8, and 9 9, With a longitudinally extending groove 12. In addition thereto. I provide each bar with a flexible clamping element or connection 13, connected at 14, at its ends tothe bar and asa sociated With tensioning means 15, Whichin this instance, are substantially of bolt formationH having shanks 16, extended through transverse'slots 17 in the bar and Winged nuts 18, for holding the bolts against sliding movement. The outer end of each of' said" bolts is provided With a head 19, which is adapted to be advanced against the connection 13, and place the saine under tension. Said head is provided With a toothed surface 20, adapted to be brought into co-acting relation with a fixed rack bar 21, on the frame bar as shown in Fig. 6. Through this arrangement the bolt 16, can be adjusted so as to advance the toothed Sufa@ .29? against the .rack bar and the re In vieivV thereof', I `do -not'desire to limit myself to the use of the inventioninconnection With emlation thus set up will positively operate to hold the head 19, against casual derangement from a selected adjusted position.

Each connection 13, is arranged normally at one side of the grooved portion of the bar.

with which it is connected so that it may be manipulated by hand and projected into the groove as shown in detail in llig. 5. rlhe grooves in the bars of said frame are preferably under-cut.

ln' use, l employ relatively stiff rods'22, around which the marginal edges of the cloth are adapted to be looped as illustrated in Fig. 5. The said marginal edges are then made to traverse the grooves in the bars of said frame and finally the flexible connections 13,'are` placed against said marginal edges and projected into the mentioned grooves 12. Under the resilient action of said connections 13, the said marginal edges of the cloth are uniformly held in secured positions upon the frame as will be readily understood. rlfhe rods 22, give rigidity to the marginal edges of the cloth and assist materially toward setting up uniformity of clamping action between the frame and the cloth.

After the flexible connections have been placed in the grooves, they may be brought under any desired 'tension by the devices 15, at the corners of the frame. rEhis arrangementis such that the cloth can be expeditiously applied to or removed Vfrom the frame; it can be uniformly held in a stretched condition, and the marginal edges of the cloth will not in any way be marred or injured through the clamping of the same to the bars of the frame.

rl`he rods Q2, are preferably of cyl'ndrical formation and each extends preferably the full length of the groove in which it is fitted. rlhe flexible clamping elements 13, are preferably non-metallic and non-corrosive. ln practice l find ordinary rope to be most s itable for the purpose for which the tensioningf connections 13, are employed.

ln the modified form of the invention shown in Fig. 7, the frame bar 23, is provided with a projection or headQel, which is equivalent of the head 19. The bar is provided with a slot 25, and operating therein is a screw 26, havingl a manipulating portion 27, at the corner bar. Said screw has swivel connection at 28, with the flexible clamping means 29. By adjusting the screw, the connection 29, can be brought under any desired tension in order that the looped portion of the 'cloth can be satisfactorily adjusted into the under-cut portion of the groove 12, hereinbefore referred to. This same operation of parts applies to the first embodiment of the invention in that under the natural tendency of the elements 13, to move toward the center of the frame, the marginal edges of the cloth will be always advanced into the under-cut portions of the cloth receiving grooves.

l/Vhat l claim is:

1. fir-n embroidery frame having a cloth receiving groove, flexible means adapted to be associated with the cloth and inserted therewith in said groove to hold the cloth in an attached condition upon the frame, and a relatively stiff bar adapted to receive the cloth in loop form and uniformly maintained contact thereof with said flexible means.

2. An embroidery frame having cloth receiving grooves, and relatively stiff elements adapted to be rolled in the marginal edges of the cloth and insertible therewith in said grooves, and flexible devices normally disposed at the sides of said grooves and insertiblo therein t0 hold said elements against casual displacement from said grooves when the cloth is stretched in the frame.

3. An embroidery frame consisting of a plurality of bars each having a groove eX- tending in one of its longitudinal faces, a non-metallic flexible clamping element carried by each bar and adapted for insertion in the groove of said bar, the groove serving to receive the marginal edge of the cloth therein, said clamping element serving to retain the edge of the cloth in said groove, and means carried by each of said bars for tensioning the flexible element thereof to regulate its pressure against the marginal edge of the cloth when .the latter is positioned in the groove, said element being adapted to occupy a position directly at one side of the groove before an application of the cloth to the frame.

In testimony whereof l aflix my signature.
